BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a cabinet cord eject structurefor a magnetic tape device integrated television receiver or astand-alone television receiver.

[0003] 2. Description of the Related Art

[0004]FIGS. 11 and 12 show an example of a magnetic tape deviceintegrated television receiver (so-called “televideo”). In this example,a cathode ray tube 2 is disposed at the upper part of a cabinet 1composed of a front cabinet 1A and a rear cabinet 1B, and a magnetictape device 3 and a chassis 5 with an AC cord 4 are disposed at thelower part of the cabinet 1. The cabinet 1 is molded of flame retardantsynthetic resin to with stand high voltages, and the chassis 5 is moldedof in expensive flammable synthetic resin, with a cord eject port 6penetrated in a rear part of the rear cabinet 1B.

[0005] An assembling procedure involves inserting the chassis 5 into therear cabinet 1B in a state where the AC cord 4 is bound by a binder 7 toeasily handle the AC cord 4 as shown in FIG. 13A, and pulling out the ACcord 4 through the cord eject port 6 and disposing the chassis 5 on abottom plate portion 1 a of the rear cabinet 1B as shown in FIG. 13B.

[0006] The above constitution has some problem in respect of accidentprevention, because the chassis 5 made of flammable synthetic resin isexposed to the outside through the cord eject port 6. Thereby, it isrequired to close the cord eject port 6 with flame retardant material inaccordance with the UL standards.

[0007] Conventionally, to solve the above-mentioned problem, a metallicplate 8 made of a flame retardant material that is opposed to the cordeject port 6 is fixed by a screw 9 to the chassis 5 to close the cordeject port 6, as described in JP-A-5-18068.

[0008] In the above constitution, the metallic plate 8 is fixed by thescrew 9 to the chassis 5 to close the cord eject port 6. However, thisfixing operation is troublesome and requires a lot of time, and becauseof the use of the metallic plate 8, the number of parts is increased.These increase the manufacturing costs.

SUMMARY OF THE INVENTION

[0009] The present invention has been made to solve the above-mentionedproblems, and it is an object of the invention to provide a cabinet cordeject structure in which a cord eject port is securely closed with asmaller number of parts.

[0010] In order to accomplish the above object, a first aspect of thepresent invention provides a cabinet cord eject structure for a magnetictape device integrated television receiver or a stand-alone televisionreceiver, including: a front cabinet molded of a flame retardantsynthetic resin; a rear cabinet molded of a flame retardant syntheticresin and having a bottom plate portion, the rear cabinet having a cordeject port in a rear part thereof; a chassis having a cord and disposedin the front and rear cabinets; and a movable lid for closing the cordeject port, the movable lid including a lid main body formed integrallyon the bottom plate portion of the rear cabinet to be openable andclosable via a thin hinge portion, an auxiliary plate projectingsubstantially at right angles from the top end portion of the lid mainbody and having a chassis opposed face, and a tab portion jutted outfrom a top of the movable lid; wherein the auxiliary plate is partiallycut away to form a cord inserting part for passing the cord; a convexportion is protruded on the chassis opposed face of the auxiliary plate,with a central through hole bored in the convex portion; a concaveportion is formed on a rear face of the chassis opposed to the convexportion, with a tapped hole formed through the center of the concaveportion in the chassis; a length of the convex portion along aprojecting direction of the auxiliary plate is set to be almost equal toa length of the concave portion, and a breadth of the convex portionalong a direction orthogonal to the projecting direction is set to beslightly smaller than a breadth of the concave portion; and the movablelid is fixed to the chassis by screwing a screw through the centralthrough hole of the convex portion into the tapped hole of the chassisin a state where the cord of the chassis is pulled out through the cordeject port and the movable lid is rotated to close the cord eject portand the convex portion is fitted into the concave portion.

[0011] The above constitution corresponds to one embodiment of theinvention (see FIGS. 1 to 9). With this constitution, the movable lidfor enclosing the cord eject port is formed integrally on the rearcabinet via the thin hinge portion, whereby the number of parts is notincreased, and the manufacturing cost is cheaper than the case where theconventional metallic plate is employed to enclose the cord eject port.Since the movable lid is formed in the shape of L-character of the lidmain body and the auxiliary plate, the movable lid having the shape ofL-character closes the corner portion from the lower face of the chassisto the rear face, except for the cord inserting port formed in theauxiliary plate, whereby it is possible to provide the magnetic tapedevice integrated television receiver or the stand-alone televisionreceiver superior in respect of the accident prevention in accordancewith the UL standards.

[0012] When the movable lid is rotated open around the thin hingeportion by using the tab portion jutted out from the movable lid, thecord eject port is opened, so that the cord is easily pulled out throughthe cord eject port. Also, when the movable lid is rotated closed aroundthe thin hinge portion, the cord eject port is simply closed with themovable lid. The cord eject port is securely kept closed by fitting theconvex portion of the movable lid into the concave portion of thechassis.

[0013] As described above, the movable lid is rotated open or closedaround the thin hinge portion, whereby the positional relation betweenthe central through hole of the convex portion and the tapped hole ofthe chassis is likely to be deviated along the opening or closingdirection. However, since the length of the convex portion and thelength of the concave portion along the projecting direction of theauxiliary plate (opening or closing direction) are set to be almostequal, the central through hole of the convex portion is matched almostconcentrically with the tapped hole of the chassis only by fitting theconvex portion into the concave portion. Thereby, it is possible toscrew the screw through the central through hole of the convex portioninto the tapped hole of the chassis efficiently and easily.

[0014] Herein, “set to be almost equal” means that the length of theconvex portion and the length of the concave portion are set in a mannerthat the movable lid is not rotated open unexpectedly after the convexportion fits into the concave portion. For example, the length of theconvex portion and the length of the concave portion may be set to beidentical. Also, the length of the convex portion may be slightly shortthan that of the concave portion.

[0015] Further, since the breadth of the convex portion is set to besmaller than the breadth of the concave portion, and there is some gapbetween the convex portion and the concave portion along the breadthdirection, the convex portion may be slightly deformed in the breadthdirection to be easily fitted into the concave portion, even if thelength of the convex portion is slightly larger than the length of theconcave portion due to a dimensional error.

[0016] As described above, since the movable lid is securely fixed tothe chassis by screwing a screw through the central through hole of theconvex portion into the tapped hole of the chassis, the movable lid isnot rotated open unexpectedly and with high safety, even though anexcessive force is falsely applied on the movable lid by the user.

[0017] Incidentally, the front and rear cabinet may be molded of a flameretardant synthetic resin such as polystyrene.

[0018] A second aspect of the invention provides a cabinet cord ejectstructure including: a cord eject port penetrated in a rear part of acabinet molded of a flame retardant synthetic resin; a chassis having acord that is pulled out through the cord eject port; and a movable lidfor closing the cord eject port, the movable lid being integrally formedvia a thin hinge portion on the cabinet; wherein the movable lid isrotated open around the thin hinge portion; the chassis is inserted intothe cabinet to be placed on a bottom plate portion of the cabinet andthe cord is pulled out through the cord eject port; and the movable lidis rotated closed around the thin hinge portion to close the cord ejectport.

[0019] With the above constitution, the movable lid for closing the cordeject port is integrally formed via the thin hinge portion on thecabinet, whereby the number of parts is not increased, and themanufacturing cost is cheaper than the case where the conventionalmetallic plate is employed to close the cord eject port. When themovable lid is rotated open around the thin hinge portion, the cordeject port is opened, so that the cord is easily pulled out through thecord eject port. Also, when the movable lid is rotated closed around thethin hinge portion, the cord eject port is simply closed in accordancewith the UL standards.

[0020] A third aspect of the invention provides the cabinet cord ejectstructure wherein the movable lid includes a lid main body formedintegrally on the bottom plate portion of the cabinet to be openable orclosable via the thin hinge portion, and an auxiliary plate projectingsubstantially at right angles from a top end portion of the lid mainbody, the auxiliary plate being partially cut away to forma cordinserting part for passing the cord.

[0021] With the above constitution, since the movable lid is formed inthe shape of L-character of the lid main body and the auxiliary plate,the movable lid having the shape of L-character securely closes thecorner portion from the lower face of the chassis to the rear face,except for the cord inserting portion formed in the auxiliary plate.

[0022] A fourth aspect of the invention provides the cabinet cord ejectstructure wherein a tab portion is jutted out from a top of the movablelid.

[0023] With the above constitution, the movable lid is easily rotatedopen or closed by grasping the tab portion.

[0024] A fifth aspect of the invention provides the cabinet cord ejectstructure wherein a convex portion is protruded on a chassis opposedface of the auxiliary plate, and a concave portion is formed on a rearface of the chassis opposed to the convex portion, and the movable lidis rotated closed to fit the convex portion into the concave portion.

[0025] With the above constitution, the cord eject port is securely keptenclosed with the movable lid by fitting the convex portion of themovable lid into the concave portion of the chassis.

[0026] A sixth aspect of the invention provides the cabinet cord ejectstructure wherein a central through hole is bored in the convex portion,and a tapped hole is formed through the center of the concave portion inthe chassis, and a screw is screwed through the central through hole ofthe convex portion fitted into the concave portion into the tapped holeof the chassis.

[0027] With the above constitution, since the movable lid is securelyfixed to the chassis by screwing the screw through the central throughhole of the convex portion into the tapped hole of the chassis, themovable lid is not rotated open unexpectedly and with high safety, eventhough an excessive force is falsely applied on the movable lid 11 bythe user

[0028] A seventh aspect of the invention provides the cabinet cord ejectstructure, wherein the length of the convex portion along a projectingdirection of the auxiliary plate is set to be almost equal to the lengthof the concave portion, and the breadth of the convex portion along thedirection orthogonal to the projecting direction is set to be slightlysmaller than the breadth of the concave portion.

[0029] With the above constitution, the movable lid is rotated open orclosed around the thin hinge portion, whereby the positional relationbetween the central through hole of the convex portion and the tappedhole of the chassis is likely to be deviated along the opening orclosing direction. However, since the length of the convex portion andthe length of the concave portion along the projecting direction are setto be almost equal, the central through hole of the convex portion ismatched almost concentrically with the tapped hole of the chassis onlyby fitting the convex portion into the concave portion. Thereby, it ispossible to screw the screw through the central through hole of theconvex portion into the tapped hole of the chassis efficiently andeasily.

[0030] Also, since the breadth of the convex portion is set to besmaller than the breadth of the concave portion, and there is some gapbetween the convex portion and the concave portion along the breadthdirection, the convex portion may be slightly deformed in the breadthdirection to be easily fitted into the concave portion, even if thelength of the convex portion is slightly larger than the length of theconcave portion due to a dimensional error.

DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENTS

[0044]FIGS. 1 and 2 show a cabinet cord eject structure 1 in a magnetictape device integrated television receiver (so-called televideo). Amovable lid 11 for closing a cord eject port 6 is formed integrally witha rear cabinet 1B via a thin hinge portion 12. Except for the aboveconstitution, the cord eject structure is almost the same as shown inFIGS. 11 and 12, so the same or similar parts are designated by the samenumerals as in FIGS. 11 and 12, and not described here.

[0045] In an assembling procedure, the movable lid 11 is rotated open(direction “a”) around the thin hinge portion 12 to insert a chassis 5into the rear cabinet 1B as shown in FIG. 3A. Then, an AC cord 4 ispulled out through the cord eject port 6, as shown in FIG. 3B. Then, thechassis 5 is disposed on a bottom plate portion 1 a of the rear cabinet1B, and the movable lid 11 is rotated closed (direction “b”) around thethin hinge portion 12 to close the cord eject port 6.

[0046] With the above constitution, since the movable lid 11 is formedintegrally with the rear cabinet 1B via the thin hinge portion 12, thenumber of parts is not increased and the manufacturing cost is cheaperthan the case where the conventional metallic plate 8 is employed toclose the cord eject port 6 (see FIG. 11). If the movable lid 11 isrotated open (direction “a”) around the thin hinge portion 12, the cordeject port 6 is opened, so that the AC cord 4 is easily pulled outthrough the cord eject port 6. Also, if the movable lid 11 is rotatedclosed (direction “b”) around the thin hinge portion 12, the cord ejectport 6 is simply closed.

[0047] The movable lid 11 includes a lid main body 11A formed integrallywith the bottom plate portion 1 a to be openable or closable via thethin hinge portion 12, and an auxiliary plate 11B rising at rights fromthe top end portion of the lid main body 11A, as shown in FIGS. 4 to 7.The auxiliary plate 11B is partially cut away to form a cord insertingportion 11 a for passing the AC cord 4.

[0048] With the above constitution, since the movable lid 11 is formedin the shape of L-character by the lid main body 11A and the auxiliaryplate 11B, the movable lid 11 having the shape of L-character fullycloses a corner portion from a lower face 5 a of the chassis 5 to a rearface 5 b, except for the cord inserting portion 11 a formed in theauxiliary plate 11B, whereby it is possible to provide a “televideo”that is superior in respect of the accident prevention in accordancewith the UL standards.

[0049] A tab portion 13 is jutted out from a top end portion of themovable lid 11, as shown in FIG. 5. The movable lid 11 is easily rotatedopen or closed by using the tab portion 13.

[0050] Along circular convex portion 15 is protruded from a circularprotrusion 14 formed integrally with a chassis opposed face of theauxiliary plate 11B, and a long circular concave portion 16 is formed onthe rear face 5 b of chassis 5 opposed to the convex portion 15, asshown in FIG. 8. The cord eject port 6 is securely kept closed with themovable lid 11 by rotating the movable lid 11 closed (direction “b”) tofit the convex portion 15 into the concave portion 16 (see FIG. 5).

[0051] Also, a central through hole 15 a is bored in the convex portion15, and a tapped hole 16 a is formed through the center of the concaveportion 16 in the chassis 5. Since the movable lid 11 is securely fixedto the chassis 5 by screwing a screw 17 through the central through hole15 a of the convex portion 15, which is fitted into the concave portion16, into the tapped hole 16 a of the chassis 5, the movable lid 11 isnot rotated open unexpectedly and with high safety, even though anexcessive force is falsely applied on the movable lid 11 by the user.

[0052] Herein, it is common that the length H1 of the convex portion 15along the opening or closing direction a, b is set to be smaller thanthe length H2 of the concave portion 16, like a comparative example asshown in FIGS. 10A and 10B. In this case, since the movable lid 11 isrotated open or closed along the opening or closing direction a, baround the thin hinge portion 12, an axial center 01 of the centralthrough hole 15 a in the convex portion 15 is likely to be deviated by adifference a between the lengths H1 and H2 from an axial center O2 ofthe tapped hole 16 a in the chassis 5, when the convex portion 15 isfitted into the concave portion 16 as shown in FIG. 10C. Consequently,it is difficult to screw the screw 17 through the central through hole15 a into the tapped hole 16 a due to the difference a, degrading theoperation efficiency.

[0053] On the contrary, according to the embodiment of the invention,the length H1 of the convex portion 15 along the opening or closingdirection a, b is set to be almost equal to the length H2 of the concaveportion 16, as shown in FIGS. 9A and 9B. Hence, when the convex portion15 is fitted into the concave portion 16 as shown in FIG. 9C, the axialcenter 01 of the central through hole 15 a in the convex portion 15 ismatched almost concentrically with the axial center O2 of the tappedhole 16 a in the chassis 5, so that the screw 17 is screwed through thecentral through hole 15 a into the tapped hole 16 a efficiently andeasily.

[0054] Also, the breadth L1 of the convex portion 15 along the directionc, d orthogonal to the opening or closing direction a, b is set to beslightly smaller than the breadth L2 of the concave portion 16, andthere is some gap β across the breadth L1, L2 between the convex portion15 and the concave portion 16. For example, each gap β may be 0.2 mm.Therefore, even if the length H1 of the convex portion 15 is slightlylarger than the length H2 of the concave portion 16 due to a dimensionalerror, the convex portion 15 may be slightly deformed in the directionof breadth L1 to be easily fitted into the concave portion 16.

[0055] The convex portion 15 and the concave portion 16 are formed inthe shape of long circle, that is, each of the convex portion and theconcave portion, in a plane view, have two straight sides opposed inparallel and two arc sides each of which connects ends of the straightsides. Therefore, convex portion is prevented from rotating with respectto the concave portion when screwing the screw 17.

[0056] Though in the above embodiment, the convex portion 15 and theconcave portion 16 are formed in the shape of long circle, the inventionis not limited to this embodiment, but they may be formed in the shapeof ellipse or rectangle, for example.

[0057] Though the so-called televideo has been exemplified above, thisinvention is not limited to the televideo, but maybe applied to astand-alone television receiver.

[0058] As was described above, according to the first aspect of theinvention, the movable lid for closing the cord eject port is formedintegrally on the rear cabinet via the thin hinge portion, whereby thenumber of parts is not increased, and the manufacturing cost is cheaperthan the case where the conventional metallic plate is employed to closethe cord eject port. Since the movable lid is formed in the shape ofL-character of the lid main body and the auxiliary plate, the movablelid having the shape of L-character closes the corner portion from thelower face of the chassis to the rear face, except for the cordinserting port formed in the auxiliary plate, whereby it is possible toprovide the magnetic tape device integrated television receiver or thestand-alone television receiver superior in respect of the accidentprevention in accordance with the UL standards.

[0059] If the movable lid is rotated open around the thin hinge portionby grasping the tab portion jutted out from the movable lid, the cordeject port is opened, so that the cord is easily pulled out through thecord eject port. Also, if the movable lid is rotated closed around thethin hinge portion, the cord eject port is simply closed with themovable lid. The cord eject port is securely kept closed by fitting theconvex portion of the movable lid into the concave portion of thechassis.

[0060] The movable lid is rotated open or closed around the thin hingeportion, whereby the positional relation between the central throughhole of the convex portion and the tapped hole of the chassis is likelyto be deviated along the opening or closing direction. However, sincethe length of the convex portion and the length of the concave portionalong the opening or closing direction are set to be almost equal, thecentral through hole of the convex portion is matched almostconcentrically with the tapped hole of the chassis only by fitting theconvex portion into the concave portion. Thereby, it is possible toscrew a screw through the central through hole of the convex portioninto the tapped hole of the chassis efficiently and easily.

[0061] Since the breadth of the convex portion is set to be smaller thanthe breadth of the concave portion, and there is some gap between theconvex portion and the concave portion along the breadth direction, theconvex portion may be slightly deformed in the breadth direction to beeasily fitted into the concave portion, even if the length of the convexportion is slightly larger than the length of the concave portion due toa dimensional error.

[0062] Since the movable lid is securely fixed to the chassis byscrewing a screw through the central through hole of the convex portioninto the tapped hole of the chassis, the movable lid is not rotated openunexpectedly and with high safety, even though an excessive force isfalsely applied on the movable lid by the user.

[0063] According to the second aspect of the invention, the movable lidfor closing the cord eject port is integrally formed via the thin hingeportion on the cabinet, whereby the number of parts is not increased,and the manufacturing cost is cheaper than the case where theconventional metallic plate is employed to close the cord eject port. Ifthe movable lid is rotated open around the thin hinge portion, the cordeject port is opened, so that the cord is easily pulled out through thecord eject port. Also, if the movable lid is rotated closed around thethin hinge portion, the cord eject port is simply closed in accordancewith the UL standards.

[0064] According to the third aspect of the invention, since the movablelid is formed in the shape of L-character of the lid main body and theauxiliary plate, the movable lid having the shape of L-charactersecurely closes the corner portion from the lower face of the chassis tothe rear face, except for the cord inserting portion formed in theauxiliary plate.

[0065] According to the fourth aspect of the invention, the movable lidis easily rotated open or closed by grasping the tab portion.

[0066] According to the fifth aspect of the invention, the cord ejectport is securely kept closed with the movable lid by fitting the convexportion of the movable lid into the concave portion of the chassis.

[0067] According to the sixth aspect of the invention, since the movablelid is securely fixed to the chassis by screwing the screw through thecentral through hole of the convex portion into the tapped hole of thechassis, the movable lid is not rotated open unexpectedly and with highsafety, even though an excessive force is falsely applied on the movablelid by the user.

[0068] According to the seventh aspect of the invention, the movable lidis rotated open or closed around the thin hinge portion, whereby thepositional relation between the central through hole of the convexportion and the tapped hole of the chassis is likely to be deviatedalong the opening or closing direction. However, since the length of theconvex portion and the length of the concave portion along the openingor closing direction are set to be almost equal, the central throughhole of the convex portion is matched almost concentrically with thetapped hole of the chassis only by fitting the convex portion into theconcave portion. Thereby, it is possible to screw the screw through thecentral through hole of the convex portion into the tapped hole of thechassis efficiently and easily.

[0069] Also, since the breadth of the convex portion is set to besmaller than the breadth of the concave portion, and there is some gapbetween the convex portion and the concave portion along the breadthdirection, the convex portion may be slightly deformed in the breadthdirection to be easily fitted into the concave portion, even if thelength of the convex portion is slightly larger than the length of theconcave portion due to a dimensional error.
